[0002] A distributor refers to a liquid distribution device installed inside a coking tower, which is a very crucial internal component in the coking tower to enable the liquid to be evenly distributed at the top of the packing layer. Therefore, a bottom feed distributor of a coking tower for needle coke production needs to be set up to meet the production requirements of needle coke. However, the existing devices still have certain defects in use, such as:

[0003] A coking tower feed distribution device disclosed in the patent number "CN202121736655.7", when in use, utilizes structures such as a flow guide cover, flow guide mesh holes, and rotating blades to enable heavy oil to be fed evenly, so as to ensure the even distribution of heavy oil in the tower and the production quality of coke. However, when in use, most of the existing distributors are integrally welded. When one of the distribution blocks is severely worn or blocked, the entire distributor needs to be replaced, and it is impossible to replace a single severely worn distribution block, and it is not convenient to install and disassemble the distributor, resulting in an increase in maintenance costs. Content of the Utility Model

[0004] The purpose of the utility model is to propose a bottom feed distributor of a coking tower for needle coke production to solve the above problems, which improves the problem that the existing bottom feed distributor of a coking tower for needle coke production cannot replace a single severely worn distribution block.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] During specific implementation: As Figures 1-5 shown, a bottom-feed distributor for needle coke production includes an annular base 1, a mounting plate 2, and a distribution block 3: A mounting plate 2 is provided at the upper end of the annular base 1, a distribution block 3 is provided at the upper end of the annular base 1, and a quick-release structure 19 is provided on the side of the distribution block 3;

[0024] The quick-release structure 19 includes a fixed block 4, a fixed bolt 5, a fixed pin 6, and a fixed hole 7. A fixed block 4 is provided at the upper end of the annular base 1, a fixed pin 6 is provided on the side of the distribution block 3, a fixed bolt 5 is provided on the side of the fixed block 4, and a fixed hole 7 is provided on the surface of the fixed pin 6;

[0025] When the device is in use and the distribution block 3 needs to be disassembled, first remove the feed groove 10 at this time, then screw out the fixed bolt 5, pull out the fixed pin 6 from the fixed block 4 through the distribution block 3 to pick up the distribution block 3, and then insert the fixed pin 6 on the new distribution block 3 into the inside of the fixed block 4, and then screw the fixed bolt 5 into the inside of the fixed block 4 and penetrate the fixed pin 6 to fix the distribution block 3, so as to perform single disassembly and replacement of the distribution block 3, avoiding the need to replace the entire distributor due to severe wear of a single distribution block 3, and greatly reducing the maintenance cost.

[0026] The fixed pin 6 is embedded in the inside of the fixed block 4, the fixed bolt 5 penetrates the fixed hole 7, and the fixed bolt 5 is threadedly connected to the fixed block 4;

[0027] The lower end of the distribution block 3 is provided with a liquid leakage hole 9, and a support rod 8 is arranged inside the annular base 1;

[0028] When the device is in use, the material falls into the inside of the distribution block 3 through the feed chute 10, and then the material is evenly leaked downward through the liquid leakage hole 9 opened at the lower end of the distribution block 3.

[0029] The upper end of the support rod 8 is provided with a fixing plate 11, and a fixing screw 12 is arranged on the side surface of the fixing plate 11, and the fixing screw 12 penetrates through the fixing plate 11;

[0030] When the device is in use and the feed chute 10 needs to be disassembled and replaced, at this time, the fixing screw 12 is screwed out, the feed chute 10 is picked up, and then the new feed chute 10 is placed between the two fixing plates 11. Subsequently, the fixing screw 12 is screwed into the fixing screw hole 15 on the side surface of the feed chute 10 to fix the feed chute 10, so as to disassemble and replace the feed chute 10.

[0031] The side surface of the fixing plate 11 is provided with a feed chute 10, the surface of the feed chute 10 is provided with a fixing screw hole 15, and the fixing screw 12 is in threaded connection with the fixing screw hole 15;

[0032] The side surface of the feed chute 10 is provided with a liquid outlet hole 14, and a liquid outlet block 13 is arranged on the side surface of the liquid outlet hole 14;

[0033] When the device is in use, first pour the material into the inside of the feed chute 10. At this time, the liquid level formed by the material moves upward. When the position of the liquid level is at the position of the liquid outlet hole 14, at this time, the material passes through the liquid outlet hole 14 and enters the inside of the liquid outlet block 13, and then the material falls into the inside of the distribution block 3 through the liquid outlet block 13, so as to evenly distribute the material downward through the distribution block 3.

[0034] The upper end of the feed chute 10 is provided with an extension block 16, the side surface of the extension block 16 is provided with a drain groove 17, and the lower end of the extension block 16 is provided with a drain pipe 18;

[0035] When the device is in use, when the material flow rate falling into the feed chute 10 is too large, at this time, the liquid outlet hole 14 is too late to leak the material flow rate. At this time, the liquid level of the material will move upward. When the liquid level moves to the position of the drain groove 17, the material flows into the inside of the extension block 16 through the drain groove 17, and then the material is discharged into the inside of the distribution block 3 through the drain pipe 18, so as to discharge the excessive material to prevent the material in the feed chute 10 from overflowing, resulting in the inability to achieve the effect of evenly distributing the material.

[0036] When the utility model is in use, the device is first installed inside the coking tower through the mounting plate 2, and then materials are poured into the feeding trough 10. When the liquid level of the materials accumulates inside the liquid outlet hole 14, the materials enter the inside of the liquid outlet block 13 through the liquid outlet hole 14, and then fall into the inside of the distribution block 3 through the liquid outlet block 13. Subsequently, the distribution block 3 is used to evenly distribute the materials.

[0037] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
